virPCIDeviceDetach would previously sometimes consume the input device object (to put it on the inactive list) and sometimes not. Avoiding memory leaks required checking beforehand to see if the device was already on the list, and freeing the device object in the caller only if there wasn't already an identical object on the inactive list. This patch makes it consistent - virPCIDeviceDetach will *never* consume the input virPCIDevice object; if it needs to put one on the inactive list, it will create a copy and put *that* on the list. This way the caller knows that it is always their responsibility to free the device object they created.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
